McIntosh MA6800 Integrated Amplifier — Grade B
£5,000.00
McIntosh MA6800 available for sale, presented in perfect technical condition and good visual shape, with only a single scratch on the top of the amplifier. The front panel has been replaced, as the original had become slightly cloudy. The unit has been thoroughly cleaned internally to remove all dust, ensuring optimal performance. A UK power lead has also been fitted, as the amplifier was originally sourced from Singapore.
We estimate this McIntosh to be manufactured around 1994, and it has had only one owner who treated the amplifier with great care. Its condition is truly remarkable for a unit of this age. This amplifier has been fully inspected, and verified to be in perfect working condition. Contact us for more information.
